The U.S. men's basketball team ended its minicamp with an exhibition that felt like a light-hearted pickup game, a much smoother ending than last summer, when Indiana Pacers All-Star Paul George broke his leg after crashing into a backboard stanchion.

"I feel so good about these four days. ... I thought our guys really responded tonight (with) a lot of effort (and) enthusiasm, they had fun," coach Mike Krzyzewski said. "They all want to be a part of USA Basketball. We had so many guys who could not play, for a variety of reasons, but even those guys throughout the week were at practices even when they weren't supposed to. Everyone did a little bit more than what they were supposed to do, and they all fit well under the USA umbrella."

While the NBA's biggest names either opted not to play in Thursday's scrimmage or weren't officially cleared to participate, those who did take part played cautiously -- and, understandably, at times timidly -- and still entertained those fans who braved a rare summer thunderstorm in Las Vegas with several highlight-reel slam dunks by some familiar names.

Los Angeles Clippers All-Star forward Blake Griffin, whose first three field goals of the second half were one-handed, monster slam dunks, said Wednesday he knew the scrimmage would be "a little bit more laid back" after what happened to George.

"Injuries are a part of the game; obviously, we feel horrible about what happened to Paul," said Griffin, who finished with 15 points, 13 in the second half. "He's such a good guy. We never want to see that happen to anybody. But you can't play with that in the back of your mind as a basketball player. It's just a part of the game."

"We made a decision, our staff, that rather than having a minicamp in the true sense of the word, and bring 18 or 20 players here, and then ask six or eight or 10 to go home -- that didn't sit well with us," Colangelo said. "We're going back to our game plan of '08, when we actually announced our team before we started our camp."

After announcing the team, Colangelo said, there will be a two-week break for the players before the national team begins preparations for Rio.

The national team, which is riding a 63-game winning streak against international competition, is aiming for a third straight Olympic gold medal.

"The culture has been established, and it's been a good one," Krzyzewski said. "A lot of people talk about what Jerry has done, or what the coaching staff has done. Really, the primary reason we have a great culture is because we have great guys, and they've been committed."
